SMC offers a range of conventional core barrel systems designed to meet the demands of various geological conditions and project requirements. The selection of a specific core barrel type depends on several key factors, including the formation characteristics, drilling depth, hole diameter, and the capabilities of the drill rig being used.
Core barrels are available in different standards and systems. The most widely used conventional types follow international specifications such as ISO 3552-1992—which includes systems like Single Tube B-type and Double Tube T2-type—as well as ISO 10097-1:1999 for wireline systems. In addition to these standards, non-standard systems like T6, T6S, and Geo-Line are commonly used around the world due to their proven performance in various drilling environments.
In conventional core drilling, as the borehole advances, drill rods are continuously added. When the core barrel becomes full—typically every 3 meters—it is necessary to retrieve the entire drill string, including all rods and the barrel, to extract the core. Drilling then resumes by reinserting the string and adding a new rod. As drilling progresses to greater depths, this repetitive extraction and insertion process significantly increases non-productive time, raising the cost per meter of core recovery.
